|
|
Hi,
after 2 years of watching DVD in 1080i with my Denon 1920 and one year HD with E1 my 1270 won't show a clean picture.
If i switch to 480/576p or 720p everything is fine but on both players the image looks like this image
The Test-pattern are clean.
A IFB-DVI-V2 is installed.
Any ideas which board it could be?
Thanks
Andreas

Update.
The probs effect every tube so i think its something wrong between input and any board before the neck-boards.
but which one. H/V-convergence is ok. Where will be the bandwith affected in this way?

I would try to eliminate any potential problems in the video source before assuming it is the projector.

Try putting the IFB card in the other slot. See if it gives you a better picture.

Like 1031 says, it looks like Sync issues to me, seen that before. In the sony menu on one of the pages (don't remember which) you can change the sync settings. I have always had the best results using H/P. Definitely change it from auto if that is where it is now.
Ya Ya, clamp is what I meant as well. Glad John remembers all the correct terminology.

It looks like a clamp setting issue. Check that CLAMP parameter is set to 'H/C' mode rather than 'Auto' when 1080i is inputed.

B.I.N.G.O.
Big kiss to you John... ah... no... but...
Without understanding why, IT WORKS. I don't know why AUTO failed but H/V works.
thx
Andreas

Glad you catch it Andreas !
Clamp 'Auto' setting is always failling on Sony CRT projectors at 1080i/p mode !! (even on my own G90 !) You'll never know why but it's like that !
